To all whom it may concern Be it known that I, Jonah. STONE, a

citizen'of the United States, residing at Chicago, in the county ofCook and State -of Illinois, have invented certain new and useful Improvements in Idotor Attachments for Harvesters, of which the 1 following is a specification My invention relates to'harvesters, and in of connecting a trailing frame withqthe frame. ofga harvester and to the manner of mountifrgna motor upon the trailing frame whereby-power may be transmitted. therefrom to operative parts pf a harvester; the object of my invention being to provide a motor attachment "that .may be readily attached to; or detached from a harvester,. strong in ite construction and eiiicient m'operation.

mechanism illustrated in the accompanying drawings, in Which 4 Figure 1 representsarear elevation of a 0 The same reference characters designate like parts throughout the various views.

. '1 represents a rear sill member of the grain platform of a harvesterfl a rear mem- 'ber'of the elevator structure, 3 a rear transarranged shaft having a driving connection.

with said transverse shaft, said shafts being mounted upon the wheel frame and hereafter designated as operativeparts of the harvester.

' 7 represents a motor supporting frame arranged'in rear of the harvester and includ- /ing afront sill member-.8 and rear sill member 9, having the grainward end thereof inclined forward and grainward'and having its end secured to the grainward end of ,frame member 8, and 10 represents a cross frame member having the opposite ends thereof secured to members 8 and 9 near their grainward ends.

secured to the upper sides of the members I 8 and 9 near their stubbleward ends, and 12 paiticular to the construction and manner".

Iattain these objects by means of the verse member of the traction wheel frame, 4;

a similar member secured to the middleof said frame'members. l

13 represents a motor having a basemember 14 secured to members 11 and 12 and including-a cylinder 15, an engine shaft 16,

having its forward end pivotally connected i with frame'member 4 of the traction wheel frame of the harvestenand its rear end secured to the stubble'ward ends of members 8 and 9 of the motor'supporting frame.

19 represents a supplemental draft memher havingits forward end pivotally con-' -nected withthe rear sill of the grain platform of the harvester by means of a universal coupling mechamsm 19, and inclinme'mbers 8 and 9.

20 represents a bracket member having opposite ends thereof secured. to members'8 and 9 intermediate members 11 and .12 and having integral therewith, near its forward end, a verticallyarranged'sleeve member 21' adapted to loosely receive the vertical stems of {a common formlof curvedcaster wheel supporting arm 22 that is provided at its lower end with a longitudinally arranged journal portion 23,-upon which is journaled a caster wheel 24. The motorframe member 9 projects at. its stubbleward end beyond the draft member'l8, and 25 represents afm0-- 9 0 tor frame member intermediate members 8 and 9, having its grainward end secured to bracket member 20 intermediate the ends I thereof and member 18, and having its opposite end in line with the-stubbleward end of 9 member 9'in'. the direction of the line of ad- Vance of the machine. I

26 represents a bracket member secured to the stubbleward ends of the motor frame members'Q and 25 and having a bearing sleeve 27 integral therewith, in which is journaled' a eountershaft 2.8 that is arranged in the direction of the line of draft, and having a sprocket wheel 29 loosely jour-. naled upon its rear end and adapted to be clutched therewith by "'mean's gof ,a clutch ;mechanism including a sliding cone 30 that is operatively'engaged with a clutch shipping fork 31 secured to the rear end of a slidiiigfrod 32 mounted upon the frame 116 mg rearward and stubbleward issecured at 75 its oppos te end to the grainward ends of sill including a sprocket wheel 36 corres )ondin" toothed clutch member ad ing frame,

members 9 and '25 and having its forward end connected with a rocking crank shaft by meansof a link 34, the rocking crank shaft beingksupported in bearings at the frontside of the motor supporting frame, and having a hand lever 35 integral therewith within convenient reach of the operator from the harvester seat.

36 represents a sprocket chain adapted to transmit motion from the sprocket wheel 17 to the wheel 2th and 3'2 a chain tightener and a sup porting arm 37'.

Theforward end of shaft 28 is operatively connected with shaft 6 of the llllls vester by means including a universal coupling 37' having a. sleeve portion 38 that slidably receives the rear end of an angular shaft 39 that inclines downward and forward, and 40 represents a universal coupling member loosely journaled upon the front end of said shaft and operatively connected with a universal coupling member 41 secured to the rear end of shaft (3. The coupling member '40 includes tion clutch member 42, and 43 represents a apted to engage therewith. slidahly mounted upon tl'reshaft 39 and yieldingly held in engagement with member 42 by means 0 a compression spring ll encircling the shaft and operative between a collar 45 secured thereto-and the hub of member L3.

In operation the trailing motor supportbeing flexibly connected with the harvester, permits the latter to be raised or lowered upon the traction wheel. or tilted, as'desired, and the caster wheel permits the trailer to accommodate itself to the line of draft of the machine. The flexible connection between the niotorand the operative parts of the harvester are such as to msure the transmission of the power of the motor thereto without cramping or undue loss from friction.

What I claim as beingmy invention, and desire to secure by Letters Patent; is:

1. In a motor attachment for harvesters, a frame comprising a plurality of parallel sill members, a draft member rigidly attached thereto and disposed in a plane at right angles "to the same, a second draft member attached to the opposite side there of and mentioned draft member, an engine mounted upon said frame. a transport wheel mounted beneath said frame, a power shaft disposed substantially parallel to said first mentioned draft member 'aud journaled in said frame, operative connections between said power shaft and said engine, intermediate said shaftand said engine, and means for operating said clutch carried by said frame and accessible from the seat of a harvester when said first mentioned a toothed fricother including a ing frame whereby it may disposed" diagonally to said first a clutch draft connection is attachedto the stubbleward side thereof and said second mentioned draft member is attached to the frame thereof at a point adjacent the cutting mechanism. 2. In a motor vester, a draft link stubbleward side thereof and extending rearward thereof, a second d'aft link pivotally attached to the frame of said harvesteat a point intermediate the ends of the cutter frame amt extending rearward and stulrbleward therefrom, a frame at-- tached to the rear ends ofsaisd, draft members and ina osed substantially iiiline with the main wheel of the harvester, a source of power mounted on said fame, and a transport wheel pivotallv connected beneath said frame disposed in the line of draft and substantially beneath said source of power. 3.
